Unpredictable pattern | Sequence&Series | JEE Adv
Hi folks, I hope you enjoyed this illustration, I tweaked it a little to make the series unpredictable, additionally, it was a fine blend of sequence and series, expansions.
In case you struggle with such types of unconventional illustrations or even conventional and necessary ones, You should try the course I took literally a year to make jeesimplified.com/set-of-60
Baki, keep rocking guys, enjoy your studies and keep drilling!

6:31 if anyone face problem in doing this basic manipulation and bringing that (r+1) term in numerator, I have a working trick for you, what you can do is equate r+1 to something variable like in this case p, it becomes r+1=p, now express value of r in terms of p, it becomes r=p-1, now you can substitute this value of r in the original quadratic equation in numerator, ofc it is more calculative, but it works always.

(r-1) factorial nhi hona chaiye tha 3 ke denominator mein

Correct ✅ Nice obs bhai! That’s a little type I made by answer still remains as its for r tends to infinity.

Mai vahi soch rha tha, abhi 11th mei aaya hun aur just cheeze samajhne ka try kr rha hun.
8:07 wouldnt the first term start from like 2? coz -1! undefined hojayega? edit: kisine already comment kiya hai, ye got it thx
At 7:00 3r^2+7r+2 ke factorial to (3r+1)(r+2) check it !

He has split to cancel no to factorize
I am now in class 11 taking biology as main stream. Always curious about mathematics.so taked maths as well but i am at ch 3.so i didn't get s lot of thing.But doon i will.😊 My pov- Thanks for making me do more hardwork. Than you
bro I like your content. Just 1 question. will you cover full syllabus for JEE 2025?
May be wrong,but shouldnt it be (r-1)! When you cancelled the terms?
at 4:15 we would have to calculate till (n-1)th term right? i got the right equation this way.
5:45 bhaiya ye sab calculation thodi easy karne ka tarika hai. Agar difference of differences 2 hota hai toh r² ka coefficient 2 hota hai, toh agar difference of differences 2k hai (here k=3) r² ka coefficient k hoga. Hence a=3 mil gaya Also, hum pretend kar sakte hai ki 12 ke pehle sequence mein ek 0th term bhi aata hai. Bas pattern continue karke pata chal jayega ki 0th term 2 hai. Ab T_0=a(0²)+b(0)+c hoga, matlab T_0=c Toh c=2 bhi mil gaya. Ab finally b nikalna bohot aasaan ho gaya, bas a+b+c=12 mein a=3, b=2 input karna hai
Bhaiya, abhi 11th mei aaya hi hun, JEE ke problems abhi solve krna start krdu ya NCERT achhe se krne ke baad karu?
Good question..Did it in 1st try
My answer is coming as 5e+5 in the end it will be 3(1+e)+4e-2(e-1) which equals 5e+5
7:58 bhiya e^x ka nhi sirf e ka taylor expansion hoga woh
Bro yaar aapke subscriber km kyo h. Voice is also great.
solved with partial fraction method :)
This kind of question is in black book S&S chapter
Nice❤
well....the solution is wrong but answer is still luckily correct because... ⅀(1 to ∞)[3/(n-1)! + 4/n! - 2/(n+1)!] *is equal to* (3e) + (4e - 4) - (2e - 4) = 5e *not equal to* (3e) + (4e) - (2e) still luckily = 5e 😅😅

yup, that’s a little error, correct cuz it was same for limits tending to 0

1 thing, ki vo dinominator me (r-2)! Hai, jisse 3/(-1)! Aa raha hai. But usse answer galat nahi hoga, kyuki ek genralised factorial function hota hai, gamma function. Usme -1 put karo to infinity ki approach karta hai. To wo term 0 ho jaaega.

Is there any way I could talk to you , i have been suffering from a problem Whenever i gave test in my coaching i just able to solve 9-10 que out of 25 but when I came home and try them , they are like piece of cake Basically me ghabra jata hu paper me aur gallat kar aata hu Bhaiya koi soln hai toh madad kardo

Bhai ek hi solution hai, jitne de sakta hai utne mock test do, aur confidence rakho. Galat hoga to ho jaaega, par confidently karo daro mat.
First sir ❤
e^x= 1/0! +1/1! +1/2!+1/3!+1/4!...
End mein mistake hai Because r ki value 1 se chalu ho rhi hai toh (r-1)! Ki value 0! Se chalu tohi toh = 3e Secind mein r! Ki value 1! Se chalu hogi toh Second term = 4(e-1) Third mein (r+1)! Ki value 2! Se chalue hogi toh = -2(e-2) All in all 3e +4e -4 -2e +4 = 5e
